Other than the lines with ".lto_discard" these look the same as the lines
above. you could combine them and only have a second prefix that only matches
those lines.

```
If you did it this way, you'd only need the one block.
Also, I'm not really following what's going on with the leading `CHECK-2-NOT:
module asm`... I'd expect that to always fail, since you have lots of lines
that do have `module asm` on them.
